BULL "WHEEL AND MOUNTING- THEREFOE.

To all whom @'15 may concern:

Be it known that l, JAMES A. CRUMLEY, citizen of the United States, residing at Charleston, in the county o-f Kanawha and State of Test Virginia, have invented certain new and useful Improve-ments in Bull lVheels and Mountings Therefor, of which the following is a. specification.

This invention relates to certain new and useful improvements in bull wheels and niountings therefor, such as are employed in connection with the drilling of oil wells and the like.

Objects of the invention are to provide a wheel of the above kind which embraces the desired qualities of simplicity, durability, and efhciency in operation; to provide a bull wheel which may be readily manufactured and assembled as well as repaired at a low cost, and to generally improve and simplify devices of this kind whereby they may meet with all of the requirements for a successful commercial use.

lith the above general objects in view and others that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination, and arrangements of parts hereinafter more fully described, shown in the accompanying drawings and claimed:

In the drawings, wheiein liker reference characters indicate corresponding parts throughout the several views:

Figure'lQ is an enlarged section on the line 12-19, of Figure. ll, partly broken away, and

F igui'e lS'is an 'elevation of one of the mounting bearings. n

Referring more in detail to the drawings, the present invention embodies a drinn or pipe section 5 upon the ends of which are mounted the wheel members 6 and 7.

Each of these wheel members comprises a split huh composed of similar longitudinal half sections 8 that are preferably cast and provided with bolt receiving 'flanges 9 midway between their ends adapted to receive the boltsl() whereby the hub sections are securely clamped together to facilitate machining thereof. These split hubs are provided with circumferential spaced and parallel external flanges il inwardly from the ends thereof and at opposite sides of the flanges 9 as clearly shown in Figure 8, and the annular flanges ll are provided with suitable openings l2 for a purpose which will presently become apparent.

Sheet metal discs 13 are disposed upon the ends of the split hub of each wheel inember against the outer sides of the annular flanges ll1 thereof, said discs being centrally apertured for snug receptioirof the ends of the hub, and the inner portions of the discs being rigidly fastened to the flanges ll by bolts lll, passing through both flanges and discs as shown in Figure 9. `Each wheel member rthus comprises a split hubV with spaced parallel disc members fastened thereon, and the outer edges of these discs are connected by means of transverse bolts l which also pass through wood cant rings 16, preferably three in number, which are arranged between the margins of each pair of discs as clearly shown in Figures 7 and 9. The only difference between the cants of the two wheel members is that one of the same has the outer two cants thereof circumferentially grooved as at 17 to form tug cants as is well known in the art.

.The bolts are of considerably greater length than the combined widths of the discs 13 and cants 16, and spacer sleeves 13 are disposed upon the projecting ends of said bolts between the heads of the saine and the adjacent disc 13, thus providing the side circular series of pins or handles used upon wheels of this character'.

The other ends of the bolts 15 have nuts` 19 threaded thereon, whereby the discs and cants are rigidly bolted together.

Gudgeons are secured within the ends of the pipe sec-tion 5 and each of the saine enibodies an integral device, the inner end portion of which is relatively large and shapedv as at 2O to have a snug ordinary iit within said pipe section, and the outer end of which is ot reduced size and of cylindrical forni as at 21, for cooperation with a suitable bearing whereby the bull wheel may beV rotatably mounted. The outer end of the larger gudgeon. portion 2O is provided with a circumferential annular flange 22 adapted to abut against the end of the pipe section 5 so as to provide a more rigid and durable con struction. The cent-ral portion 21 ot each gudgeon may be connected with the portion 2O thereotl by means of integral radial webs or spoke members 23 as shown in Figure 2, and the gudgeons are preferably fastened in place by riveting as atQOa.

In assembling a bull wheel of the above construction, the pipe section 5 is drilled with the proper holes, and then the gudgeons are fitted and riveted in place. Then the discs 13, cants 16, and hub 3 are assembled by bolting at 14 and 15, the bolts 15 being drawn tight and the bolts 14 being leit loose for allowing the hub section to separate sothey can be slipped onto pipe 5. The hubs are then securely bolted to pipe 5 by a pair of crossed bolts at each end of each hub as at 24, and then the bolts 14 are tight cned for securing the discs rigidly against the hub flanges 11. The bolts 10 are only used when the hubs are being machined and the iianges 11 are braced against the action of bolts 14 'by the ears or' flanges 9 and transverse ribs 25 connecting the iianges 11 between the flanges 9.

A novel form of tlyer 26 is mounted on the pipe 5 between the heads 6 and 7 so as to divide the wheel into two portions, respectively, upon which may be wound the slack portion ot the cable and the portion oi the latter which is actually in use, as is well known in the art. This flyer embodies a plurality of reeling arms disposed tangentially of the pipe 5 and each including an inner section 2? ot channel iron and an outer section or bar Q8, preferahlv of wood and pointed or tapered as at 29 at their outer ends. The flanges ot the sections 27 are directed outwardly and the webs thereorn disposed against the pipe 5, the inner ends o1" sections 27 being closed as at 30 and abutting against the webs of each other. The inner end portions of the outer arm sections are positioned 'within the inner arrn sections and are secured in place by boltsr 31 and 3Q, each bolt 32 being passed through the inner ends oi av pair of opposed arms and the pipel 5, entering both sections of said arms. T he bolts 31 are provided in pairs, each pair passing through the sections of one arm and the inner end wall 30' of the arm abutting against the side thereof.

The bull wheel above described isv rotatably supported by a special mounting consisting oi a pair ot posts, one arranged at each end o the wheelA and each having a bearing for reception of one of the gudgeon portions Q1. As shown in Figures 11 'to 13, each post consists orn a piece of pipe 33 notched at one side of its lower end as at 34 to form a seat for the derrick floor sill' 35 which is of channel torni and disposed with its flanges horizontal andv projecting outwardly, the notch being on an incline so that the post will occupy an inclinedy position, and the sill being secured to the post by a bolt 36 passed through the web of the sill and through the post. A circular opening is formed in a side of the post 33v as! at 37 tor snug reception of a long hollow boss 38 formed on one side ot a bearing plate- 39, the inner side of which is concaved to lit against the post as at-'40. The plate 39 projects above and below the opening 37 and' has openings 41 through which bolts 42 pass,- the bolts 42 passing through the post vfor rigidly securing the bearing plate thereto. The plate 39 has a transverse opening 43, the wall of' which is lined as at 44 by durable bearingl metal, and said opening forms lthe bore of the boss 38 and the bore of a shortboss 45 formed on the outer side of the plate 39. A lug 46 is formed on one sideedge of plate 37 and this lug has a passage that opens at the top thereot1 and that 'communicates with an inclined passage through the adjacent portion of the plate and the lining 44 as at'47. Means is thus provided for facilitating oiling of the gudgeonrportions 21 disposed in the openings 43 of the respective bearings. The upper ends of the posts 33 are slotted or biturcated as at 48 tor reception of the ends oi a tie or brace rod 49 which is secured in place by a U-bolt 59 passing through one leg oit the bifurcation and around said rod. From the above description it will beseen that have provided a very simple and du rable form of bull wheel and mounting which may be cheaply and easily manufactured and placed in use, and whichV may be repaired from time to time if found necessary, with facility and ease.
